Lincoln said, in this piece here, he says... he frees the slaves; he
said, "All slaves in armed rebellion." The slaves. Now understand one
point: the African is not a slave, that's one point that they didn't
realize when they were writin this. The African is not a slave. The
African has a history far more advanced than this nineteen-ninety
history we're in right now. He's not a slave. Lincoln's ultimately
sayin now you were born a slave, you'll always be a slave, and all I
will ever see you as is a slave, and I free you.
